IMPROVEMENT IN SEEDlNG-MACHINES.

Specification forming part of Letters Patent No. 34,747, dated March 25,1862.

To all whom it may concern:

Be it known that we, JAMES R. FINOH and THOMAS W. HENDERSON, of Dayton,in the county of Montgomery and State of Ohio, have invented certain newand useful Improvements in Seed-Planters; and we do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

In the annexed drawings, making a part of this specification, Arepresents a substantial lrame, which is supported upon an axle providedwithwheels, as is usual in seeding-carriages of this description.

Upon the frame is secured a seed hopper or box, 13, which is providedwith seed-openings in its bottom at suitable distances apart. Run.- ninglongitudinally of this box is a shaft, O,

-which has its hearings in the ends of the box,

and which is provided with two irregularlyshaped wheels, D D. Theperipheries of these wheels are provided with a zigzag or canishapedflange around their centers, while upon each side of this cam ortlangelugs project, as shown in the figures. These wheels revolve with theshaft 0, and, being situated immediately over the seed-openings in thebottom of the box, they serve to stir the grain, working it from side toside over the openings for the purpose of preventing clogging and formaking the machine distribute regularly. 'A gear-wheel upon the end ofthe shaft G catches into a gear-wheel upon the main shaft or axle of themachine, and by this means the shaft 0 is made to revolve.

Upon the under side of the boxB are secured three slidesf Two of theseslides are seen in Figure 2, and are marked E and F. They are made tofit together, as shown, so that when they are moved longitudinally inditt'erent directions one or more seed-openings are formed at pointswhere they separate. A lever, 01, moves a bar, b, which is pivoted tothe crosspiece a on the under side of the box, which causes the twoslides to move simultaneously in different directions. The third slide,00, is

situated below the other two, and is provided with two or moreseed-openings, as may be required. This slide is moved backward andforward longitudinally by means of a lever, m. The lever d has securedto it a bar, a, which has a screw, 0, attached or formed upon one end,over which nuts pass for stationing the bar n and lever d in any desiredposition.

G is the drag-bar, and H the boot through which the seed falls, andwhich makes the furrow. The boot and bar are secured together by meansof a rod, J, which passes through them, as seen, and then forms the axleof 3.

' the boot to a bar behind the seed-box, whihh bar may be revolved forthe purpose of winding up the chain, and thus raising the said boot fromthe earth.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-- 1. The employment of the wheelsD Deprovided upon their peripheries with thezigzag or cam flangerepresented, and with the lugs a a, arranged and used upon the wheelwith the flange, as is herein fully set forth, for th purpose specified.

2. Pivoting the boot H to the drag-bar G through the ear at the upperfront end of the said boot by means of the rod J, which carries theroller I behind the boot, substantially as and for the purpose setforth. I

In witness that we claim the foregoing we have hereunto set ourhands inthe presence of witnesses.
